Bandage applicator

ABSTRACT

The present invention relates to a sheet material applicator comprising a clindrical body rotatable within a housing, the housing forming a handle for the applicatior, and means at one end of the cylindrical body for mounting a roll of the sheet material particularly a bandage applicator.

[0001] The present invention relates to an applicator for a sheet material, particularly to a bandage applicator allowing the comfortable and precise placement of the bandage by a person alone.

[0002] At the present time, bandages are applied by hand, thus making it necessary to unroll the bandage with the fingers as the bandage roll is passed around the area to be protected.

[0003] This is inconvenient and inappropriate, particularly in the application of bandages by the patient, especially when there is a deficiency in dexterity of the fingers, with the additional problem that, even in the case of experienced personnel, it is difficult to achieve a homogeneous level of tension in the bandage.

[0004] According to the present invention, there is provided a sheet material applicator comprising a cylindrical body rotatable within a housing, the housing forming a handle for the applicator, and means at one end of the cylindrical body for mounting a roll of the sheet material.

[0005] In a preferred embodiment, the sheet material applicator is a bandage applicator.

[0006] The bandage applicator in the present invention alleviates the problems described in a simple manner as it allows the bandage to be applied, even by the patient himself or herself quickly, easily and flexibly, without requiring the bandage to be unrolled with the fingers while the bandage is being applied. In addition, it has certain devices to ensure the optimal regulation of the tension in the unwinding of the bandage.

[0007] In accordance with the present invention, the applicator comprises a main cylindrical body, preferably open at one of its ends, presenting two peripheral projections and certain means for attachment, at its non-open end, intended for the placement of a tubular part. On the periphery of the latter, the end of the bandage is attached and the bandage is wound around the tubular part. The said part may be made of a single segment or in various segments.

[0008] The tubular part may be placed by inserting it through either end of the applicator, thus making it possible for the same to turn and the bandage to be unwound under the most favourable circumstances, even if the user changes hands or the direction in which the bandage is unwinding.

[0009] The means of attachment mentioned above are made in such a way as to make the movement of the main part and the tubular part interlocked and turning at the same time. The said means of attachment are preferably made from a cylindrical portion sticking out from the main part at its non-open end, into which some longitudinal slots are made on the sides, intended for the insertion by means of grooving and tonguing of certain internal ridges present on the inside of the tubular part.

[0010] On one of the projections of the main body, two half-casings are inserted by means of grooving and tonguing to act as the handle of the applicator, so that by holding the same by means of the handle it is possible for the main body and the tubular part to turn and for the bandage to unwind.

[0011] The other projection comprises a braking area for stopping the movement of the bandage as it unwinds, preventing or slowing down this movement by means of pressure on this area with a finger or any other mechanical element, preferably presenting this are certain small studs so as to enhance this braking function.

[0012] The invention will now be more particularly described with reference to the drawings in which:

[0013]FIG. 1 shows a side view of the bandage applicator included in the present invention;

[0014]FIG. 2 shows a one-quarter cutaway drawing of FIG. 1; and

[0015]FIG. 3 shows a perspective drawing of the parts involved in the bandage applicator included in the present invention.

[0016] The applicator 1 of the present invention comprises a main cylindrical body 2, one of the ends of which is open whereas the other end has a cylindrical extension 4 fitted with certain longitudinal slots 5 around its periphery. The main body 2 has around it a projection 6 on which two identical and opposing half-casings 7, 8 are attached by means of grooving and tonguing when certain studs 9 are placed in certain opposing housings 10.

[0017] The half-casings provide a handle for the applicator allowing the main body 2 to turn. On the extension of the said body 2 a tubular portion 11 is attached by grooving and tonguing as it has certain longitudinal ridges 12 which fit into the slots 5, making the turning of the tubular part 11 and the main body 2 an interlocked movement.

[0018] The bandage 13 is rolled around the tubular part 11, attached to the same by means of an adhesive element 14 on one end, with the bandage having another adhesive element at the other end 15 to allow the beginning of the bandage to be found.

[0019] The tubular part 11 may be attached to the extension 4 by means of either of its two ends, thus favouring at all times the holding of the applicator in a more comfortable way for the better unwinding and turning of the bandage, by merely changing the end which is inserted as the bandage is applied.

[0020] The main body 2 has another projection 16 on its periphery, on the outside edge of which there are certain transverse linear ridges 17 to facilitate the braking, by means of the pressure of a finger, the rotating movement of the main body 2 as the bandage unwinds, in order to regulate the tension of the bandaging.

[0021] Having sufficiently described the nature of the invention, as well as the manner in which it may be implemented in practice, it must be noted for the record that the provisions indicated above and illustrated in the attached drawings are liable to modifications in detail insofar as the same do not change their fundamental principle. 

1. A sheet material applicator comprising a cylindrical body rotatable within a housing, the housing forming a handle for the applicator, and means at one end of the cylindrical body for mounting a roll of the sheet material.
 2. An applicator according to claim 1 wherein the cylindrical body comprises, in a region adjacent the handle, a first projection which, when pressurized by a digit in use of the applicator, brakes rotation of the cylindrical body within the housing.
 3. An applicator according to claim 1 or claim 2 which is a bandage applicator.
 4. An applicator according to any one of claims 1 to 3 wherein the housing is cylindrical and concentric with the cylindrical body.
 5. An applicator according to any one of claims 1 to 4 wherein the cylindrical body comprises a second projection inside the housing for preventing longitudinal movement of the housing with respect to the cylindrical body.
 6. A bandage applicator comprising a main cylindrical body fitted with two projections on its periphery and, on at least one of its ends, means for attachment of a tubular body made of one or more parts, which tubular part may be fitted by either of its ends in such a way as to make rotation of the cylindrical body and the tubular body an interlocked movement.
 7. A bandage applicator according to claim 6 wherein on one of the peripheral projections of the cylindrical body, two half-casings are attached to provide a handle for the applicator.
 8. A bandage applicator according to claim 7 wherein the turning movement of the main body is independent with respect to the handle.
 9. An applicator according to claim 7 or claim 8 wherein the other peripheral projection of the main body carries means for allowing the braking and regulation of the tension and unwinding of the bandage.
 10. A bandage applicator according to claim 9 wherein the means allowing the braking and regulation of the tension and unwinding of the bandage comprises studs provided on the surface of the braking area on which pressure may be exerted by the fingers of the hand.
